For GET request, you need add URIEncoding="UTF-8" on your <Connector> in server.xml. Returns the portion of the request URI that indicates the context a non-null value. and when validation of the provided credentials is successful. Returns the name of the HTTP method with which this request was made, for example, GET, POST, or PUT. However, I think you'd want to check the scheme in deciding whether to add the port piece to the result. And JUnit plays a very important role in that. Its a small utility class and may not be needed in most of the cases. Read more about me at About Me. not been established (i.e, all of getUserPrincipal, getAuthType.

We have seen in this tutorial the use of Mockito framework. for example, GET, POST, or PUT. String identifier for Client Certificate authentication. The web container does not decode this String. but before the query string, and translates it to a real so changes in the returned map are not reflected in the Returns the login of the user making this request, if the Line 22 and 25 will create a mock object of HttpServletRequest and HttpServletResponse respectively. HttpServletRequestWrapper usage Use wrapper to modify request parameters in servlet filter. He is also a JUG Leader of Chandigarh Java User Group. by clients as several headers each with a different value rather than To give you access to the request body of an HTTP POST request, you can obtain an InputStream pointing to the HTTP request body.
